How about offering people the chance to automatically decline DCC (dynamic currecny conversion) transactions. i.e. if the transaction type is a face-to-face environment (get from POS entry mode?) and the merchant country (get from card acceptor name/location) does not equal the relevant transaction currency and the customer has chosen to decline such transactions.
I would love this. For something that is apparently a benefit to consumers, DCC makes me sad whenever I realise I’ve experienced it.
Obviously it would only work with online authorised transactions but I assume that is most of them at the moment - will this change once you are offering debit cards?
